CO and CO2 measuring instruments

The CO2 content of the area is used as a measure of the air quality. Muggy, used air makes you tired and has negative effects on staff performance. With Testo measuring instruments, you can assess the indoor air quality on the basis of the combined measurement of the CO2 content, temperature and air humidity via spot or long-term measurements.

Air flow measurements in ducts, temperature measurements in laboratories, humidity measurements in production, pressure difference measurements in clean rooms. The testo 480 digital temperature, humidity and air flow meter is a one stop solution with a wide range of optional sensors which equips you to measure, analyse and log these and a variety of other parameters with only one device.

The testo 435-2 indoor air quality meter allows you to carry out all the measurements that are necessary to check and adjust ventilation and air conditioning systems and assess the indoor air quality. The IAQ meter also offers a wide range of probes and sensors to equip you to measure various parameters.

testo 435-3 – multi-function climate measuring instrument with integrated differential pressure measurement. You can use this to carry out measurements for adjusting ventilation and air conditioning systems and assess room air quality. For this we offer a comprehensive range of optional probes and sensors to choose from.

Includes Pitot tube for differential pressure measurement for filter monitoring or for measurement

Further optional probes can be attached: thermal and vane anemometers, along with probes for air humidity, CO2, absolute pressure and temperature

You can keep a close eye on indoor air quality with the testo 445 climate measuring instrument: the allrounder can measure up to 6 parameters (with the appropriate probe), which can help you make a professional assessment of indoor air quality. The climate measuring instrument therefore supports you in adjusting and checking ventilation and air conditioning systems.

Multi-function climate measuring instrument: measure up to 6 measurement parameters at the same time

testo 435 is a series of multi-function measuring instruments by Testo amongst which the testo 435-1 version is the entry-level measuring instrument in this series which can be used to carry out measurements which you need to adjust ventilation and air conditioning systems and assess air quality. With the instrument is offered a comprehensive range of optional probes and sensors to choose from.

Optional thermal and vane anemometers for measuring air velocity and volumetric flow in ventilation ducts

Air quality: measurement of CO2, air humidity, air temperature and absolute pressure with the optional IAQ probe

Carbon monoxide is a killer. That’s why CO checks need to be carried out when a gas heating or boiler is being serviced or installed. The compact testo 317-3 CO detector is designed to provide you with a quick and reliable means of testing the surrounding air for carbon monoxide.

If there are a lot of people in a room, the air quality deteriorates. Reliable monitoring is particularly important, because indoor air quality is linked to our well-being. The WiFi data logger testo 160 IAQ is ideal for monitoring indoor air quality in facility management.

Ideal for monitoring indoor air quality (IAQ)

Simple to install, integrate and operate – particularly user-friendly with air quality displayed in the form of a traffic light system

Use this practical Indoor Comfort ComboKit to handle all relevant measurements in order to evaluate the indoor air quality in indoor areas and to determine the draught risk and degree of turbulence in workplaces. The testo 440 air velocity and IAQ measuring instrument, the CO2 probe with Bluetooth including temperature and humidity sensor and the turbulence probe are all safely stowed away in the case. So you can get down to work straight away!

Intuitive: clearly structured measurement menu for long-term measurement and parallel determination of CO₂ concentration, humidity, air temperature and degree of turbulence in workplaces

Precise: calculation of wet bulb temperature, dew point and absolute humidity – determination of the degree of turbulence and draught risk according to EN ISO 7730 / ASHRAE 55

Precise, reliable measurement of all air velocity and IAQ parameters with just one measuring instrument: the multifunction measuring instrument features intuitive operation with clearly structured measurement menus. Adjusting air conditioning and ventilation systems, monitoring air quality or carrying out comfort level measurements – thanks to versatile options for combining with high-quality, digital probes, you are ideally equipped to carry out your measuring task (please order probes separately).
